I share in Las Fotos de los Lectores de La Vanguardia these photographs taken in Roses, in the Alt Empordà region, from La Punta beach and from Nova beach.
In the images we can appreciate some photogenic and surprising lenticular clouds over a Mediterranean Sea quite choppy by the north wind, which blew reaching gusts of up to 88 km/h.
The lenticular cloud is shaped like a lentil, as its name indicates, or a saucer or converging lens. They are stationary and form at high altitudes in mountainous areas and isolated from other clouds.
Among mountaineers, these lenticular-type clouds are considered a harbinger of a storm, although the truth is that there is still a lack of rain in Catalonia.
In addition, on the one hand, glider pilots continually look for these types of clouds because the atmospheric system that forms them involves large vertical movements of air and, on the other hand, airline pilots avoid them due to the turbulence created in air systems. rotor.
